ARRANGEMENT FOR MOUNTING TWO COAXIAL SHAFTLINES

摘要

The invention concerns an arrangement with two concentric shaftlines (15, 16) one of which overlaps the other, wherein a gasket-bearing sleeve (38) interposed therebetween is conical and supported on a spacer (40) of the outer shaftline, so that a nut (19) for mounting the front end is accessible from the rear passing through the gap (43) between the two shaftlines (15, 16), thereby enabling the nut to be unscrewed and the outer shaftline to be dismounted. The invention is applicable to front bearings of high pressure shaftlines of gas turbines and enables the high pressure body to be dismounted from the rear, without having to further detach components such as a fan at the front of the machine. The arrangement does not prevent a meshed gear (20) from being mounted.
